Application May 11, 1956, Serial No. 584,245

2 Claims. (Cl. 30-91) This invention relates to the class of tools andmore particularly to a novel cable slitter.

The primary object of the present invention resides in the provision ofa cable slitter which is made of a nonmetallic substance and which isadapted to fit the hand of the user in a highly convenient andcomfortable manner.

An additional object of the invention resides in the provision of acable slitter which employs a deformable flap so as to enable pressureto be brought on a cable by merely squeezing the entire device. 1

One of the features of the invention lies in the pro vision of a cableslitter having a recess therein with means for holding the entire devicein an assembled state holding a plurality of blades in the recess.

Still further objects and features of this invention reside in theprovision of a tool of the class described which is simple inconstruction, efiicient in use, inexpensive to manufacture, which may beused to cut the outer covering of non-metallic sheet cable in aconvenient manner.

These, together with the various ancillary objects and features of theinvention which will become apparent as the following descriptionproceeds, are attained by this cable slitter, a preferred embodiment ofwhich has been illustrated in the accompanying drawing, by way of example only, wherein:

Figure 1 is a perspective view of the invention shown ready for use as acable slitter;

Figure 2 is an elevational view of the invention with one part of thebody removed and with the fasteners holding the parts of the bodytogether being shown in section; and

Figure 3 is a sectional detailed view as taken along the plane of line3-3 of Figure 1.

With continuing reference to the accompanying drawing wherein likereference numerals designate similar parts throughout the various views,reference numeral generally designates the cable slitter comprising thepresent invention. This device includes a body 12 which may be formed intwo parts as at 14 and 16. The body is provided with an arcuate channel18 therein adjacent the end 20 of the body 12 and extending the fulllength of the body. Openings 22 and 24 are, of course, formed in thebody with the opening 22 being of somewhat larger dimensions than theopening 24 and with the channel 18 extending substantially the fullwidth of the body 12. The channel 18 is arcuate in shape and forms aflap 26 at the end 211) of the body with the flap 26 being deformable.Because of the shape of the channel 18 as well as the shape of the body,adjacent the opening 22 there is provided a thickened portion 28 whichis movable with the deformable flap 26 and forms a part thereof yetwhich in itself is comparatively rigid.

The body parts 14 and 16 are so shaped as to form recesses as at 32 and34 for reception of a blade 36 such as a razor blade or the like.Further, the recesses 32 and 34 may be of larger size for reception of areinforc- 2,819,520 Patented Jan. 14, 1958 ing plate for rigidifying theblade 36. The blade 36 is so arranged that an edge 38 thereof willextend into the channel 18 so that upon application of pressure on theflap 26 by gripping the entire body, upon sliding the entire body alongthe cable the edge 38 of the razor blade cuts the outer covering of thecable.

Holding the blade 36 in position are a pair of bolts db and 42 which arepreferably countersunk. If the bolts as at d-tl and 42 are suitablycountersunk, and with the body 12 being formed of a suitablynon-metallic electrically insulative material, the entire device may beelectrically insulative.

in addition to the recesses 32 and 34 being formed in the body, anotherrecess 44 may be formed therein for reception of a plurality of spareblades 46 which may be held in place by fastener 43 which also may becountersunk as desired. Oppositely disposed to the. end 20 of the bodyis the end 50 of the body which is preferably corrugated to formfinger-grips as at 52, 54, etc. These provide means whereby the entiredevice may be conveniently grasped without slipping.

In practice, the cable is inserted in the channel 18 and pressure isapplied on the body by squeezing the hand. This pushes the flap 26towards the other portions of the body. When this is done, the cable ispressed against the edge 3? of the razor blade 36 and then by slidingthe device along the cable to be slitted, the razor blade cuts the outercovering of the cable.

From the foregoing, the construction and. operation of the device willbe readily understood and further explanation is believed to beunnecessary. However, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction shown and described, andaccordingly all suitable modifications and equivalents may be resortedto, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

1. A cable slitter comprising a body, said body having a channel thereinadjacent one end thereof with said channel extending the full length ofsaid body and extending substantially the full width thereof, saidchannel being arcuate in shape and forming a deformable flap at said oneend of said body, the other end of said body being corrugated andforming finger-grips, said body being formed of a non-metallic material,a blade disposed in said body and having a cutting edge thereofextending into said channel.

2. A cable slitter comprising a body, said body having a channel thereinadjacent one end thereof with said channel extending the full length ofsaid body and extending substantially the full width thereof, saidchannel being arcuate in shape and forming a deformable flap at said oneend of said body, the other end of said body being corrugated andforming finger-grips, said body be ing formed of a non-metallicmaterial, said body being formed in two parts, a blade disposed betweensaid parts, and means securing said parts together, said means securingsaid blade in said body with an edge thereof extending into said channeloppositely disposed to said deformable flap.
